misses. y 1

T all 'whom it may concern iof Be it known that I, @Hannes T. FnAN'iz, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in T pe-Writing Ma chines, ofwhich the fo lowing is a full, clear,`and exact specification.

My vinvention relates particularly to a tabulatiiig attachmentfor typewriting ina- ,i chines, and-one of its objects is the provision of simple and kefficient mechanism of this character whereby the carriage may be released from its feeding mechanism, gradually stoppedat the end of its run and ar`- rested in its return movement at a predetermined point.

A .further object of the invention is the provision of a locking out device in combination with a butler vwhich will effect a gradual 'stoppin of the carriage at the end of its run an there-connection of the saine with the feeding mechanism after lthe carriage has returned to a predetermined position.

Another object of the invention is the provision `of a tabulating attachment for type writing machines i comprising a resilient buffer for relievin the impact of the carriage and mounte `to actin oppositionto the motor spring of the typewriting machine 4 and comprising also a locking out device for maintaining connection between `the bntfer device and the carriageuntil the latter' is returned b v said buffer device against the action of the motor spring to' a predetermined position.

Other objects ofthe invention will a pear hereinafter, the novel combination o? elements being set forth in the appended claims.

proximately the point where the carria e is to be stopped; and Figs. 9 and 10 are views of ainodification.

Similar parts are designated by like referC ence characters throughout the various views.

Referring to the drawings, 11 designates the base of the typewriting machine, 12 the table of the supporting frame, 13 the back bar of the carriage 14, to which the latter is pivoted and along which it slides in the usual way. Pivoted to the back bar 13 independently of the carriage buty connected to move therewith is a frame 15 which carries the escapement rack 16. Cooperating with this rack are spacing dogs 17 which are connected to spacing keys 18. Under the action of the main spring 19, which is connected in any desired manner at 20 to the carriage 14, the latter is fed step by step under the coni trol of the spacing mechanism. These parts are constructed and operated in a manner` well understood in the `art to control the movement of the carriage while operating "the typewriter keys in the ordinary way.

of which are in this instance shown,` alj though the number may be varied as desired. That is to say, one of such levers may be used alone, or two ormore of them may be used, depending upon the operation desired. These levers are suitably spaced apart by means `of washers 25 and the upper portions of such levers are guided in slots 26 in the outer end of the plate 27 which is rigidly attached tothe upper end of the angular bracket 22 to occupy a substantially hori-y zontal position. To the lower end of each of the levers 24 is pivoted at 29 a push rod 30 which extends along under the machine through the guide openings 31 to the front of the machine and to the outer ends of the rods are connected the keys 32.

iii),

A U-shaped sprin 33 connected to the bracket: 22 bears on t e levers' 24 and urges them against the ixed stop 34. This spring may be made sufficiently strong to alone perform this function, but if desired, the springs 35 may be added, one end of each being attached to t e base 11 and the other ends being connecl ed to the push rods at 36'. If desired, the spring 33 may be omitted and the s rings used alone.

Fixed to tlie rear of the table 12 at 68 is an angular plate 37, which is provided with an opening 38 of special contour, as indicated in Fig. 5, to accomplish one of the objects of the lnvention. This plate is an important feature of my invention, as it effects the stopping of the carriage at exactly the point predetermined. lt should be noted that this plate is rigidly iixed to the frame of the typewriting machine, as are also the horizontal guide plate 27 and the supporting bracket 22, and therefore these parts never move while the plate 37 is acting as the locking out plate.

Back of the plate 37 are two longitudinal rods 39 and 40, the ends of which are fixed to the supporting standards 43, 43 which in turn are rlgidly attached to the rear of the table 12 of the typewriter frame, as indicated in Figs. 6 and 7. These rods extend parallel to the esca-pement rack bar 16 and the back pivot bar 13 of the machine, and are for the pur ose of guiding and supporting the buffer lock 41. The upper rod 40 also carries the buii'er spring 42 between one end of the buer block 41 and the slidable ring 45, the latter being used in connection with a set-screw 44 to adjust the tension of the louder spring 42. It is evident that the buier spring 42 tends to move the buffer block to the right, as viewed in Fig. 6, but the extent of thisanovement is limited by Athe stopping ring 45 which may be held in adjusted position by the set-screw 46. As will be explained hereinafter the buffer nblock ymust occupy a certain definite posi tion with respect to the locking out plate 37 and such position is secured by varying the position of the limit stop 45".

As indicated-in Fig. 2 the action of the buffer spring is o posed to that of the me torr spring 19 of t e typewriter and its tension is adjusted to bey sufficiently greater than that of the motor spring to return the carriage to its proper position after the buffer block is struck. The tension of the main spring is also adjustable lin the well known manner.

In'the upper portion of the buffer block 41y are four vertical slots which may be cut into the material of the block. These slots extend from the front to the rear and are adapted to receive the flat lates or plun* gers 47, 48, 49 and 50 which perform several. functions. Each of these plungers is arrasa@ mounted to slide in its res ective slot inde pendently of the others an each is provided with a short laterally extendlng pin 51. Against each of these pins `bears the upper end lof a spring 52, there being one spring,

tionsor inoperative positions of these plungers is such that the locking lugs referred to are entirely back of the plate 37 so that u on lateral movement of said plungers with the buffer block, the plate 37 will not interfere. As shown, these locking lugs are of diderent` heights and are initially directly behind the 'opening 38 in the locking plate 37 so as to be op osite the respective steps 54', 55', 56 and 5 Therefore when the parts occupy the ositions indicated in Fig. 5 any one of the p angers may be thrust fflirward through the openlng in the locking p ate.

The front ends of the lungers in the buffer block are each surfaces or cams 59 or engaging and lifting the longitudinal bar or 'rod 60, which is connected to the escapement rack frame 15 and carries stops or striking members 61,

62 and 63 movable along the rod 60 and ca' gable of being fastened in adjusted position y means of set-screws, as indicated. These striking members areintended to he set at points corresponding to the predetermined positions where the carriage is to stop in the operation of tabulation. It should be noted that there may be a plurality of such striking` members so that the carriage may be stopped at a corresponding number ofpplaces ures are toA be tabulated on a single pae. If desired, the tabulator bar 60 may e notched laterally to receive U-shaped stops or striking members, as is well understood by those skilled in the art.

When one of the plungers is operated and a cam 59 engages the rod 60 to lift the frame*V 15 together with the rack bars 16, the latter through the same transmits motion to the buffer block against the action of the bader sprin 42. When this happens the rear `shoul er of the locking lug 54 moves in front of that portion 63 of the metal plate rovi ed with inclined los rio j where, for instance, several columns 'of iig- A tit ian

' shown merely by Way of illustration of the j 37 just to the left of the steps as viewed in Fig. 5. In this view,the`dash1ines indicates the positions of the plungers just after the plunger' a7` has been struck, `the locking lug 54 being in front of the locking portion 63 of the plate 37 so that the plunger' 47 cannot be returned to initial position until the buffer spring forces the louder block to `the position where the escapement rack may be permitted to fall to stop the carriage at the desired point. It will therefore be seen that the stopping mechanism is maintained in connection with the carriage until the buffer spring returns the carriage to the predetermined point Where it is to stop or come to rest in readiness' for the operation of the typewriting keys to effect writing in columns in a minimum space of time. When thev locking lug 54 assumes the position indicated by the dashdines in Fig. 5, the other locking lugs are behind thelockingplate as indicated by the dotted lines. j

It should he particularly noted that the only addition to the parts which move the platen of the typewriter is the rod 60, which carries the striking members, the buffer block and the buffer spring, together with the stopping plungers and locking plate be` ing connected directly to the frame of the machine. The added momentum of the carriage due to the tabulator attachment is,

therefore reduced to a minimum. AL though the tabulator is herein shown connected to a typewriting machine of the Remington type it should be understood that it may be applied to other kinds of type-` writers, the Remington type being herein invention.

The operation of the tabulator may be explained as follows: During the ordinary operation of the typewriter, the keys 18 are struck and the type bars operated in the usual Way to effect the advance of the carriage step by step by the main spring 19 and the eseapement mechanism. When tabulations are to be made accurately and in a minimum space of` time, the various parts are properly adjusted and one of the auxiliary keys 32 then actuated. 'In the corr struction illustrated four such keys are intended to be used but it should be understood that only one such auxiliary key would be used where only one stopping plunger is employed. I have shown a series of four of such plungers and therefore there should be four keys, one corresponding to each plunger. Furthermore if two or more plungers are used they should be spaced apart such a distance that the lateral face of one plunger is a letter space distant from'the corresponding lateral face of the next succeeding langer. a

lf the left hand auxiliary key is operated the plunger 4.7 will-be thrust forward-- tol cause the cam face` 59 to lift the rod 60 and thus disconnect the feeding mechanism from the carriage, whereupon the latter will jump from wherever it happens to be tothe place where the carriage is to ultimately stop and at this point the'striking member 61 will engage the outer endA of the plunger' 47 `and through the buffer block compress the spring 42. This will cause the carriage to come to a stop gradually but the spring 42 being stronger than the motor spring of the typewriter, a re-bound will take place, but during this re-bound the locking lug 54 coi operating with the locking plate '37 `revents the return of the plunger 47 and tierefore the connection between the latter and the carriage is maintained until the carriage returns to the position where it is to be stopped or the operative connection of the feeding mechanism is to be restablished just as soon as the locking dog 54 returns to the step 54', the spring 52 Willautomatically return the plunger provided the tabulating key has been released This will cause the bar 60 to be released and the rack bar 16 to fall. It will be noticed that the main spring acts in o position to the buffer spring and therefore a sorbs the recoil of the buffer s ring. This recoil may not be entirehr a sorbed in every instance, it being sutilcient to absorb it to such an extent that after the plunger is disengaged from the striking member on the rod (30, the movement of the carriage will not be continuedl as much as a letter space.

I will 'now explain `the various adjustments which should be made to secure this operation. lf it is desired to write a column of figures, the carriage is first set at the desired point where the first numeral is to be Written and while held in such position the stop (il is adjusted so as to just contaetthe plunger 50 when thrustforward through the'opening in the plate 37. As already explamedthe right hand face of the plunger 47, for instance, is letter space distantr from the right hand face ofthe plunger48andso on, so that when the carriage is moved one step farther along such stop 48 willjust con'- tact with the left hand face of the striking member 6l when the plunger 48 is thrust forward. The same is trueI with respectjto the plun ers 49 and 50 or any additional number hat may be used. As arranged the apparatus is convenient `for tabulating lcolumns of figures of hundreds, tens, yunitsjand decimal points, so that when the right hand key 32 is actuated` thevcarriage will jump to the hundreds place and three figures,a decimal point, and two more figures may b e Written. By pushing thelnext keyi ,tonthe left, the carriage will stopat thetens place; by operating the third key from the right the carriage `may be Vstopped atthe units place; and by operatingv thefextreme left U tion corresponding to the decimal points.

After one set of figures in one column are written, one or more sets of figures may be written for succeeding columns on the same page in the same line. For instance, after operating one of the tabulating keys and. writing the li res for the corresponding column, one o such keys may be operated again to secure a further jumping of the carriage so that another striking member, as that designated 62 on the rod 60, will imlpin e against a plunger of the stopping mec anisni to eiect a stopping of the earriage at the desired point for the figures in the next column. The striking member 62 is adjusted in the same manner as that designated 61. And if the third column is to be written the striking member 63 is to be adjusted in the same manner. If the bar is notched laterally as hereinbefore referred to, such notches are so arran ed that each will be a letter space distant rom the next succeeding one and in such event the U- shaped striking members may be located at the points corresponding' to the point where the carria e is to be stopped.

Prefera 1y the main spring is rst adjusted tohave the proper tension for operating the carriage step by step with a force to suit the operator. 'lhe tension of the buHer spring 42 is then adjusted so as to be only as much stronger than the main spring as is necessary to bring the bulier block, stop plunger and carnage back to the position where the connection between the escapement rack bar and the escapement pawls is to be restablished. That is to say, the buiier spring is put under such tension that after gradually stopping the carriage the latter will be returned by it against the aetionof the main spring and be brought to a stop at or about the time the plunger flies back to initial'fI position and allows the escapement frame to fall. The buder spring must be suiciently strong under any oirculnstances to return the carriage to the position where the locking lugl can slip under its step in the locking plate 37. Thebu'er sprlng should therefore return the butter block and carriage to such position that the formerwill abut'against the limit stop 45 on the rod 40. The tension of the spring 42 may be varied by sliding the ring 45 along the rod 40 and fastening it in the adjusted' position by means of the set screw44, and the position of the abutment 45 may be va'- ried in a similar manner. It will be evident that if the buffer spring is under too great tension, it will tend to recoil too strongly, so that when the buiiier block strikes the stop 45 and the plunger releases the escapement rack, the carriage will tend to continue to move bv momentum and move too far before the rack rengages the pawls.- By proper ananas the carriage automatically stopped at the required point. H, however, the auxiliary key is held in Until after the carriage finally comes to rest, the upper end .ofthe lever 24 may oder an obstruction against the complete return, of thej.plunger so that the extension 47 will come back aga-inst the side of the 'upper end of the lever-214 holding the latter by friction so that theft'abulator key will have to be pulled back ,to initial position. Obviously the spring 33 may be made suiiiciently strong to overcome this diiiculty, so that even when this occurs the apparatus will operate to stop the carriage at the desired oint and all the parts will be restored at t e proper time to their initial ositions in readiness for the next operation. l

f it is desired, however, not to have a strong spring 33 or 35 so that the tabulatorkeys may be operated more easiiy, the extensions 54, 55, 56 and 57 may be provided with tail pieces64, 65, 66 and 67 respectively, so that the upper end of the lever 24 will be held continually in connection with `the plun er during the operation of the stopping mec anism so that after the plunger returns to initial position the lever 24 is absolutely free to return to its initial position when rel leased. rthis modieation is shown in- Figs. 9 and 10. Fig. 9 also indicates that the upper ends of the levers 24 are U-shaped so that the tail pieces referred to will not be moved by the lever other than that with which it is intended to coperate. it will also be noticed that the extensions 47', 48', and, 49 are arranged diagonally and the levers 24 are of d1iiterent lengths so that after a plunger is thrust forward and is then moved laterally by the impact of the carriage, the upper end of the operated le'- ver 24 will not abut against'the next extension 48', but the latter will simply pass over the same. j

Although ll have shown the vertical width of the left hand portion of the opening 38 as uniform and alittle greater than the vertical width of the plungers ofthe stopping mechanism and the vertical width of the right hand portion of the opening 38 variable as indicated, I wish it to be understood that li do not desire to be limited to this exact construction, as such opening 38 may be made of .various shapes or contour and still fall within the spirit and scope of nism to prevent the arrestmg of the carriagev my invention. Sa, also, those skilled in the art may make various changes in the details and arrangement of other parts of my invention as defined by the claims and I wish therefore not to be limited to the precise construction herein disclosed.
